CNC system programming instruction

1. Loop program. The G71 outer circular rough car cycle instruction is applicable to the outer cylindrical surface or inner hole surface with a long axial size, which requires multiple cuts to complete roughing. However, the application of this instruction has its limitations, that is, the contour of the part must conform to the direction of the X axis and the Z axis at the same time monotonously increasing or monotonously decreasing.

2. FANUC specifies 2 digits/4 digits after address T, and the code signal and selected communication number are sent to the machine tool to select the tool on the machine tool. A program segment can only specify one T code. For the number of digits that can be instructed after the T address and the correspondence between the T code and the machine tool operation, please refer to the manual of the machine tool manufacturer.

3. CNC Computerized Numerical Control Machine (cnc) is an automated machine tool equipped with a program control system. The control system can logically process programs with control codes or other symbolic instructions and decode them, so that the machine tool can operate and process parts. It is also called CNC or CNC machine tool.

4. The code of CNC programming is as follows: G code is the instruction in the CNC program. It is generally called the G instruction. Using G code, you can realize fast positioning, inverse circle interpolation, forward circle interpolation, midpoint arc interpolation, radius programming, and jump processing.

5. Instruct the numerical control system to change the tool, and use the address T and the following 4 digits to specify the tool number and tool compensation number (tool bias number). The first two digits are the tool serial number: 0~99, and the last two digits are the tool compensation number: 0~32. After each tool processing, the tool compensation must be canceled.

How is the automatic programming of CNC machine tools realized?

1. Run the program: start the CNC machine tool, automatically control and adjust the machine tool through the controller, and complete the processing process. In this process, real-time monitoring and adjustment of the machine tool is required to ensure the processing accuracy and stability. Inspect the finished product: After the processing is completed, inspect and test the finished product to ensure that its quality meets the requirements.

2. Return to zero. Before the knife, you must return to zero (return to the origin of the machine tool) in order to clear the coordinate data of the last operation.Note: All three axes of X, Y and Z need to return to zero. The spindle rotates forward. Using the "MDI" mode, the spindle rotates forward by entering the instruction code and maintains a medium rotation speed.

3. Use CAD/CAM software to realize automatic programming of modeling and images. The most typical software is Master CAM, which can complete the programming of milling two-coordinate, three-coordinate, four-coordinate and five-coordinate, turning and wire cutting. Although this kind of software has a single function, it is simple and easy to learn, and the price is low. It is still the choice of small and medium-sized enterprises at present.

What system do programmers use for programming

1. Linux is usually the most commonly used operating system in network security. This is because Linux is not easily attacked by viruses, and its system is very well maintained, so there is very little chance of vulnerabilities in the system.

2. Operating system: Most programming software is developed on operating systems such as Windows, macOS or Linux. Choosing a suitable operating system can ensure the normal operation and ease of operation of the programming software. Monitor: The higher the resolution, the clearer the display effect.

3. Operating system: usually commonly used operating systems such as Windows or Mac OS X. Monitor: Dual monitors are better than single monitors. Developers usually need to use multiple tools and applications at the same time for development work.

4. Yes, but it is recommended to use a Windows tablet. If you want to learn programming, you can't use a tablet computer. At least you have to use a laptop orIt's a desktop, because you have to install some programming software, and then some programming code writing, you have to use the keyboard to operate.

5. **Operating system**: Most programmers use Windows, macOS or Linux operating systems. Choosing an operating system that you are familiar with and suitable for programming can improve work efficiency. **Portability**: If you need to go out to work or attend meetings frequently, it will be more convenient to choose a lightweight laptop.
